Thanks for this investigation, mark49! I yet have to update the DriverPacks with the nF 4 Intel Edition drivers, but DriverPack LAN is already updated with them. And you're correct, these ethernet drivers are NOT (completely) compatible with nForce 3/4. Not at all with nForce 2, but that was already the case for the nForce 4 AMD Edition drivers. I'll add the nF4 Intel drivers now to DP Chipset and DP MassStorage.
